Description
Technical field
The present invention relates to a kind of natural plants pigment and its preparation method and application.
Background technique
Organic pigment has the advantages that wide color gamut, color clear, tinting strength, tinting power are outstanding, but compared with inorganic pigment, valence
Lattice are expensive, and durability, in terms of there are problems.But in daily production and life, organic compared to inorganic pigment
Pigment is more favored and favorable comment.Organic pigment is mainly used for coating, ink, rubber, fiber, paper processed, leather, cosmetics etc..But
The organic pigment for being synthesis is all that chemical method obtains mostly, and raw material water solubility synthetic dyestuff is mostly with chemical industry such as benzene, toluene, naphthalenes
Product is raw material, is formed by a series of organic reactions such as sulfonation, nitrification, azos, contains R-N, N-R ' key, phenyl ring mostly
Or xanthene structural compounds, thus many synthetic organic pigments have certain toxicity, it is necessary to strict control using kind, range and
Quantity limits acceptable daily intake (ADI).
Some organic pigment long-term low doses intake, there is also teratogenesis, it is carcinogenic a possibility that.Compared to the organic face of synthesis
Material, natural plant dye is nontoxic, ecology, and color is soft, certainly however characteristic, and it has good Environmental compatibility and medicine
Object health properties, thus be concerned, especially become the new lover of colorant in cosmetics, medicines and health protection, juvenile product field,
There is vast potential for future development.
It is most of that dyestuff is extracted by heating by water or solvent from the point of view of the dyeing of current natural plant dye,
And dye liquor is directly used in the dyeing of textile.The method has a disadvantage that 1. dye moiety is thermally decomposed, and stability is poor；②
The sublimation characteristics of natural plant dye are destroyed；3. it is perishable, it should not store；4. reproducibility is difficult to grasp.To solve
The above problem, 108795096 A natural plants color lake Chinese invention patent application publication number CN and preparation method thereof, middle promulgated by the State Council
Preparation process, color lake and its application in bright 108864744 color lake A patent application publication number CN will be natural using color lake technology
Vegetable colour makes its precipitating become natural plants color lake by metallic compound precipitator, improves the stability of vegetable colour with it, protects
Matter phase and reproducibility.But this method just with the complexing of metal ion be dye molecule combine formed it is big insoluble
Property particle, structure is still unstable, and granular size is unable to control during forming particle, the particle generally formed
All larger, this brings difficulty to subsequent coloring application.Appoint at present and so lacks a kind of stable, size tunable, coloring energy
The strong natural plants pigment of power and its preparation method.
